This place is GREAT!.
My wife is from Singapore and we vacation alot in Thailand. We are always trying to find good, real asian food here in Utah.
Bangkok Grill is by far the best in Utah County that we have found (we have been to EVERY asian place we could find!)
You can't go wrong here. If you don't do spicy, then they let you custom the heat to your comfort level. My wife likes the soups, while I go for the satay and pad thai. Definitly try the sweat mango rice.
